IMPROVEMENT IN SAWlNG-MACHINES.

Specification forming part of Letters Patent No. 156,160, dated October20, 1874; application filed May 4, 1874.

roller and at its opposite end with a bevel gear wheel, which mesheswith a pinion adapted to receive movement by means of a disk on theshaft of said pinion being brought into frictional contact with a diskor pulley on the operating-shaft, and said pinion being capable of areverse movement by causing a third pulley or disk controlled by ahand-lever to come into frictional contact with the pulleys or disks, ashereinafter described.

In the drawings, Figure 1 is a plan "iew of my improvement; and Figs. 2and 3 are side elevations of the same, looking from different sides ofthe machine.

The letter A represents the base of the machine, at one end of which isa toothed roller, B, journaled between guides at a on the base A. To thesaid roller is connected one endof a shaft, 0, which is provided at itsopposite end with a bevel-gear wheel, D, the end of the shaft beingjournaled in a cross-head, E, attached at its ends to bars or rods Fpivoted to standards Gr. A shaft, a, is also journaled between said barsF, and provided with a pinion, H, which meshes with the bevel'gearwheel, as shown; and the journal of said pinion is extended beyond oneof the bars F, and is provided with a pulley or disk, I, which can becaused to rotate in frictional contact with a pulley or disk, K, on theend of the operating shaft L,,which is journaled in the end of themachine, and provided with a fiy-wheel, by which motion is imparted tothe several Working parts of the machine. To a vertical post orstandard, M, is pivoted a lever, N, having a horizontal arm, I), and anarm, 0,

curved downwardly, and provided with a book, 01, which embraces theshaft 6. Said shaft is pivoted at one end to a post, f, and is providedat its other end with a disk or pulley, g, by which means the said shaftcan be brought into contact with the disk K on the operating-shaft, andbe removed therefrom by raising or lowering the said lever, the purposeof which will hereinafter appear.

The operation of my invention will be readily understood.

When motion is imparted to the operatingshaft it will revolve the diskK, and by depressing the disk Iwhich is done by depressing the lever Nand causing its foot h to bear on the bar F, thus forcing the same downand causing the disks I and K to be in frictional contacttl1e pinion His revolved, and the gear-wheel D and toothed roller B operated to movethe lumber forward. In order to reverse the movement of the lumber thelever N is raised, when a spring, 0, will throw the bars F upward,raising the disk I from contact with the disk on the operating-shaft,and cause the disk 9 on the pivoted shaft 0 to come in contact with thetwo disks I and K, said disk 9 thus serving to communicate the 1110-tion to the pinion and bevel-wheel. It will thus be seen that, when thedisks are in the position last described, the disk K will impart motionto the disk g in the direction of the arrow, Fig. 2, and it will, inturn, impart motion to the pulley I in the direction of the arrow onsaid pulley in Fig. 2, thus reversing the motion of the pinion and ofthe toothed Wheel, and carrying the lumber backward.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination, with the roller 13, its opcrating-shaft, and bevel-gearwheel, of the pinion H and disk I, carried by the pivoted bars F, andthe lever N, provided with the disk g, for operation, in respect to thedisk on the operating-shaft L, substantially as and for the purposesdescribed.
